Quinonoid constituents as contact sensitisers in Australian blackwood (Acacia melanoxylon RBR).
Australian blackwood (Acacia melanoxylon RBR) is a valuable commercial timber that since 1925 has been incriminated as being injurious to health. In addition to toxic effects numerous cases of allergic contact dermatitis and bronchial asthma have been observed in woodworkers. Several constituents have been identified in recent years, but none of them could be considered as aetiological factors....
متن کاملHierarchical patterns of correlated mating in Acacia melanoxylon.
Pollen of acacias is transported by insects as polyads, composite pollen grains. The polyad has enough pollen grains to fertilize all ovules within a flower and hence all seed within a pod may be full sibs. Isozyme markers were used to test this hypothesis in two populations of Acacia melanoxylon R.Br. The proportions of fruit pods with multiple paternity detected in two populations were 0.08 a...
متن کاملPhenotypic Variation of Indigenous Sesame landraces in Urmia Climate
Sesame is one of the oldest and most important oilseeds in Iran and the world due to its nutritional value. In the present study, 25 sesame landraces collected from different regions of the country were evaluated in terms of phenological, morphological and physiological traits in Urmia climate. The ANOVA results showed that there was a statistically significant difference between the landra...
متن کاملTWO METHODS FOR TREE VOLUME ESTIMATION OF Acacia melanoxylon IN PORTUGAL
Two models were developed to evaluate total volume under and over-bark of Blackwood (Acacia melanoxylon R. Br.) stand trees. By variance analysis regarding volume with and without bark it was confirmed that trees age is responsible for 48 to 50% of its volumetric behaviour. Considered the averages of those variables and regarding the three homogeneous groups of the studied sites, a single model...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
